$\mathrm{O}$ is the centre of a circle, and its radius is $5 \mathrm{cm}$. Where does $\mathrm{P}$ lie, when $\mathrm{OP}=5.2 \mathrm{cm}$.

$\mathrm{O}$ is the centre of a circle, and its radius is $5 \mathrm{cm}$. Where does $\mathrm{P}$ lie, when $\mathrm{OP}=5 \mathrm{cm}$.

$\mathrm{O}$ is the centre of a circle, and its radius is $5 \mathrm{cm}$. Where does $\mathrm{P}$ lie, when $\mathrm{OP}=4.8 \mathrm{cm}$.

Draw two circles one having radius $6 \mathrm{cm}$ and other having $3 \mathrm{cm}$ as shown in the following figure such that the inner circle passes through centre of the other circle.

Draw two circles of equal radii with centres $A$ and $B$ such that each one of them passes through the centre of the other. Check whether $AB\perp CD$.
